Research Activities
In the research field “Complex Liquids” we study structure and dynamics of soft matter, in particular colloidal and aqueous systems. The main focus lies on coherent X-ray scattering experiments at modern synchrotron and free-electron laser sources.
These experiments are performed with custom-made sample systems synthesized in our group and are accompanied by different characterization methods (UV-Vis, DLS, TEM, …) as well as molecular dynamics, Brownian dynamics and Monte Carlo simulations.
In the frame of this research project we study ultrafast phenomena using modern free electron x-ray sources. Our research portfolio includes investigations of ultrafast demagnetization, quenching of the resonant magnetic scattering signal, all optical switching, and development of novel and science enabling split-and-delay X-ray optics.
Our experiments are performed at various free-electron laser facilities including LCLS, SACLA, FERMI and FLASH. We have developed an end-station for pump–probe small-angle X-ray scattering experiments at FLASH. Static characterization of our sample systems via small-angle X-ray scattering and Fourier transform holography is performed at 3rd generation storage rings.
The in-house synthesis includes a broad range of nanomaterials, such as semiconductor, metal, dielectric, magnetic, polymeric particles of different sizes and shapes. The synthesis is carried out by wet chemical methods and results in nanostructures with a narrow size and shape distribution.
